Letters Patent No. 74,061, dated February 4, 1868.

MOVEMENT In some r012. HEATING WATER.

TO ALL WHOMfIT MAY CONCERN:

Be it known that I, J01!!! ELLIS, of White Plains, in: the connty'ofWestchestcr, and State of New York, have invented anew and improvedBoiler for Heating Water'; and I do hereby declare that the following isa full, clear, and exact description thereof,.which will enable othersskilled in the art tomake and use the same, reference being had to theaccompanying drawings,'form ing a part of thisspecification, in which-Figure 1 represents a front elevation of my improved-boiler.

Figure 2 is a longitudinal vertical section of the same, the plane ofsection being indicated by the line. a: :r, fig. 1. p

Figure 3 is a transverse sectional elevation of the same, the plane of.section beinglindicated by the line ea s 2. t

Figure 4 is a transverse sectional elevation of the same, the plane ofsection being indicated by the line z z, fig. 2. V 1

Similar letters of reference indicate corresponding parts.-

- This invention relates to a new boiler-for heating water forbuildings, green-houses, and other similar purposes, and consists inarranging a series of horizontal pipes between two hollow heads, in sucha manner that the water will flow at least twice through'the tubes, soas to'be very completely heated. The boiler is not covered with orsurrounded by the ordinary expensive iron-plates, but the pipes aresimply ail-ganged in brickwoi-k, and some of the pipes form the grate ofthe boiler, The whole device is thus ver'ysimple and (tempera ti velychca'pthe whole boiler actually consisting only of the two headsand ofthe pipes connecting the same.

A represents the front head of the boiler. Thesame is made of doublesheet-metal wells, so as to be hollow, as shown in fig. 2, and isprovided with a hole, a, through it for the. insertion of the fuel. Thehead A may also be cast into the required form; This hole can be closedby a fire door, b, as shown. B is the rear head of the boiler, made alsoof double shcet-metal plates, so as to be hollow, and has also'a hole,a, through itfor the-escape of'the smok'e. The head B can also be castinto the required shape. If desired, the'rear head can be made withoutthe hole e,'the smoke escaping between the pipes, connecting the heads,to a suitable chimney. C C are a series of pipes, 'made of wrought orcast iron, or other suitable material. Their ends are fitted into theheads A and B, respectively. The whole furnace is built under a brickarch, and is sur-' rounded by brick walls, as is clearly indicated infigs. 1 and 2. The interior of the front head A is, by means of one ormore plates; (or cores,) d, divided into two or more compartments. 4

The water enters the lower part of the front head through a pipe orpipes, D, and, rising inthehead, flows hack to the rear head throughthose pipes, C, which communicate with the lowerv compartment of thehead A If only one partition, d, is in the head-A, the head 13 will bewithout a partition, sothat the watcrmay rise in the head B, and mayilow in the upper pipe 0 to the upper compartment of the head A, whenceit is conducted oif'through pipes E. It the head A is divided by plates0! into three or more compartments, the interior of the head B will alsobe subdivided by similar partitions, so that a still more frequentcirculation of'thc water from one head to the other will be eii'ected.The fire is kindled upon the lower pipes C, whichare close enoughtogether to enable the draught to circulate through tlie iire. The lowerpipes are arranged nearlyon a semi circular line, as shown in figs. 3and 4, so that the fuel will always fall to the centre, and infallingwill be cleared of ashes. Any kind of fuel may be used in this boiler.Peat, wood, coal,'or cok'c can be employed. Having thus described myinvention, what I claim as new, and desire'to secure by Letters Patent,is

The boiler for heating water, consisting of the two hollowheadsconnected 'by the tubes, and having no metallic sides or walls, thegrate-bars being also tubulurfsaid heads subdivided into compartments,so that the water shall circulate freely through the boiler, as hereindescribed, for the purpose specified.
